Why Your Nest Thermostat Isn't Running Right and How to Solve the Problem

April 13, 2021

The Nest thermostat is one of the top-selling smart thermostats on the market today. And for good reason. It picks up on your temperature preferences and makes an energy-efficient schedule to match. And using geofencing with your phone, the Nest Learning Thermostat and Nest E are aware of when you’re at your residence or out and about and can change settings to help you save even more.

The Nest works with a vast range of 24-volt heating and cooling systems, but it’s always a smart idea to check the Nest thermostat compatibility checker before purchasing one. Don’t forget to check with your energy supplier for valuable rebates, since you could be able to get a Nest for free or close to it.

Once you’ve confirmed it’s compatible, you can either install it without help or call a HVAC pro like WM J Kraus & Son. If you’re wiring it yourself, you’ll notice a terminal for the C-wire, or common wire. This wire is solely used for powering your thermostat. If your house or HVAC system is older, you might not have one of these wires. Most of the time, Nest says this isn’t a problem because the thermostat can draw enough power from other heating and cooling wires.

In some cases, your heating and cooling system might need that C-wire. And here’s why.

Why Your Nest Keeps Losing Power and Other Malfunctions

The Google Nest Thermostat is an improvement from outdated programmable thermostats that rely on a combination of wiring and AA batteries for power. It has a rechargeable lithium-ion battery and wiring to sync with Wi-Fi, power its digital display and operate your heating and cooling system.

8 Common Nest Thermostat Issues

If it can’t draw enough power, Nest says you may have some of these problems:

  1. Bad battery life.
  2. Thermostat motion sensing won’t work.
  3. Your thermostat occasionally disconnects from Wi-Fi.
  4. Your system suddenly turns on or off, or won’t turn off.
  5. Your system is making odd noises, such as chattering, stuttering, clicking or thumping.
  6. Heating or cooling is short cycling, or frequently turning on and off in a short period of time.
  7. There is a delay notice on your Nest thermostat’s screen, such as “heating is delayed for 2:30 minutes.”
  8. The system fan is constantly on, won’t turn on or turns off and on rapidly in a short period of time.

You may believe something is up with your heating and cooling system, but if you just started using the Nest, we suggest you start with your thermostat initially. This is especially true if the weather is moderate, and you haven’t been relying on your heat or air conditioning frequently.
